FLIER FOR SPINNING MACHINES AND THE LIKE.

Application filed April 9, 1925. Serial No. 21,819.

This invention relates to improvements in the fliers employed in connection with spinning machines.

The chief object of the invention is to provide a fli r of this character with a freely gyrating, unchangeable bearing which is unaffected by the type or size of spindle to which it is applied.

Another object is to provide the flier with self-contained means for readily attaching it to the spindle and independent means forming a perfect bearing or journal upon which the flier rotates.

In the accompanying drawings: Figure 1 is a side elevation of the improved flier in position on the spindle. Figure 2 is a top plan view thereof. Figure 8 is an enlarged vertical longitudinal section on line 33,

2. Figs. 4 and 5 are detached perspective views of the attaching member or anchoring sleeve and the journal for the flier block or body, respectively.

Similar characters of reference indicate corresponding parts throughout the several views.

Referring now to the drawings, indicates a spindle of the usual tapered form and 11 a bobbin mounted thereon.

In its general organization, this flier consists of a flier-body or block upon which the customary flier wires are mounted, a bearing upon which the flier-body is revolubly mounted, and a self-adjusting attaching member or anchoring sleeve for securing the flier to the bobbin-spindle. The flier-body is, by preference, in the "form of a substantially hollow block, consisting of a cup-shaped base-section 12 and a top section 13 fastened together by a lap or interlocking joint. These sections may be stamped from sheet metal to provide an external bead or shoulder 14 between the top and bottom of the block. Alining central openings 15 extend through the block-sections and surrounding the same are inwardly-facing rims or collars 16 whose opposing ends terminate short of each other to provide an intervening annular groove or channel 17.

The flier wires or arms 18 are, by preference, detachably connected to a base-plate 0r spider 19 which fits tightly over the lowerblock section 12 below the head 14;. In its upper side and at opposite endsthereot, the base plate is provided with wire-retaining loops or eyes 20. The outer end of each flier wire has the usual thread-engaging eye 21, while its inner end has a laterally-offset or bent portion 22 arranged to lie flatwise on the base plate between the flier-body and the opposing end of the respective retaining loop. The flier wire is reliably clamped in position by a rotatable locking ring 23 disposed between the base plate and the head 14 of the flier-body. At its'diametrically 0pposite sides, said locking ring is provided with vertically-offset flanges 24 which overlap the bent portions 22 of the flier Wires in the locked position thereof, the vertical webs 25 of said flanges serving to deflect such bent portions of the flier wires laterally to hold the latter in their retaining loops 20.

Fitter: within the flier-body opening 15 is a bearing-member or sleeve 26 upon-which the flier-body is free to rotate. This bearingsleeve preferably consists of a vertically '5 split band of spring steel having an annular external thrust collaror head 27 disposed substantially centrally between the upper and lower ends thereof. Above and below this bead, the bearing-sleeve has turned, ex-

ably consists of a vertically-split, expansible band 29 of spring steel provided between its ends and on opposite sides thereof with external bosses or projections 30. This band fits comparatively loosely within the bearing-sleeve 26 and its projections form thrust-bearings which engage the annular, internal groove 31 resulting from the external head 27 of the bearing-sleeve, there being suiiicient play between these complemental parts to allow a limited movement of the flier-body and its bearing lengthwise of the anchoring-sleeve. The diameter of the bearing-sleeve 26 is somewhat larger than that of the anchoring-sleeve to allow for the expansion of the latter as it is applied to the spindle and at thesame-time permit such freedom of movement of the flier both laterally and longitudinally of the spindle as to insure uniformity of tension and twist under all Working conditions.

By constructing the ther in this manner,

an unchangeable bearing is provided about .7

mounted.

I claim as my invention:

1. A flier for the spindles of spinnin machines, comprising a flier-body, a bearing member contained Within said body and about which the same revolves, and means contained -Wllil1l11 said bearing member for attaching the flier to a bobbin-spindle.

2. A :flier for the spindles or spinning machines, comprising-a flier-body, abearing of practically permanent diameter contained Within said body, and an anchoring member of variable diameter arranged Within said bearingfor attaching the flier to a bobbinspindle.

3. A flier-block for a bobbin-spindle, including a bearing member about which the block revolves, and a combined supporting member and anchoring sleeve for the flier contained Within the bearing member and adapted to grip the spindle.

l. A flier for the spindles of spinning machines, comprising a flie1=body,a hearing sleeve therefor, and a supporting anemmember for attaching the flier to a boobinspindle. 5. A flier for the spindles of spinning machines, comprising a flier-body, a bearing member contained Within said body and about which the same revolves and anexpansible supporting sleeve contained within said bearing member for attaching the flier to a bobbin-spindle.

6. A flier for the spindles of spinning 1nachines, comprising a flier-body having a central opening, and a pair of concentrically arranged members contained Within said body opening, the outer member constituting a bearing on Which the flier-body revolves and the inner member constltutlng a means for attaching the fliertoa bobbinspindle.

7. A flier-block for a bobbin-spindle, 1neluding aselt-adprstmg, sleeve adapted for attachn'ient to said spindle, and a bearing sleeve for the flier-block surrounding said attaching anemberaand in spaced relation thereto.

8. A-fiier-bloclsfor a bobbin-spindle, including a supporting member adapted for attachment to said spindle, a bearing member tor tl16 fll6IblOCl surrounding said sup porting member and in spaced relation thereto, and means-tor limiting the endwise movement 0t said members relative to each other.

9. A flier-bloclrtor a bobbin-spindle, in cluding a self-adjusting sleeve adapted for attachment to said spindle, a bearing sleeve tor the flier-block surrounding said attaching member,- one of said sleeves having a projection andthe other a complemental groove for receiving said projection to limit the endwise movementoi' said sleeves relative to each other.

10. A flier tor the spindles of spinning machines, comprising a flier-body, a bearing sleeve contained Within said body and about which the same revolves, means on said bearing member for limiting the endwise movement of the filGEEbOCly thereon, and an expansible supporting sleeve contamed withing andsupported on said bearing sleeve for attaching the flier to the bobbin-spindle.

11. A flier for the spindles of spinning machines, comprising a flier-body, a hearing her loosely arranged Within said bearing centralopening and an annular groove tacing said opening, a: bearing-sleeve for said body arranged in its opening and having a thrust collar engagingv said groove, and an expansive attaching-sleeve contained With-e in said bearing-sleeveand adapted to grip a bobbin-spindle.
